I like the design. I do have a couple of things though.
Dont see the point of having those bottom borders above the "CMS - Content Management System Live Demo" either make them one border but for me they have a break in them. So they are two separate lines.
Also for the contact form when you are on another page (besides home) and you dont input any information and you click send it brings you to the home page.
And not too sure about the Domain Checker, I think you could add more styling in there and possibly a button of some sort? Thats just me!
